playsink: Switch to faster pad linking methods

Browse source 
Logic for choice of GST_PAD_LINK_CHECK_* is as follows:
* Where return of pad_link wasn't checked before : NOTHING
* Where linking is between known compatible elements : NOTHING
* All other cases : TEMPLATE_CAPS

Slashes down playsink reconfigure by up to 50% cpu time.
